Taped on TDK D90 (Type I) cassettes with Dolby C NR from 95.5 WPLJ-FM/New York by Ron Gerber. The "Mix Of The Decade" aired from 4 PM until midnight on New Years Eve, December 31, 1989. I managed to catch the last 6 hours and 45 minutes of the full 8 hours; I was taping Hot 97's Top Dance Songs Of The '80s countdown, and I switched from Hot 97 to WPLJ as soon as it ended at 5:15 PM. There are several breaks where I had to flip the tapes.
The Mix Of The Decade was put together by Hot Mix; from the Hot Mix website: "Before the start of the first weekly show of 1990, HOT MIX created an 8-hour program called "Mix Of The Decade 1980-89", which ABC agreed to distribute to kick off the new partnership on January 1, 1990. "Mix Of The Decade 1990-89" was distributed on Vinyl disc to over 100 radio stations."
I have never run across another copy of the Mix Of The Decade, and I would be very interested in a more pristine or complete copy; if you or someone you know has one please contact me through the contact link at www.crapfromthepast.com.
This is monstrously huge, and is utterly fantastic. Hope you dig it. -Ron
